We knew which games were going to be part of this year's XBLA "Summer of Arcade" -- but not when. Today, Microsoft shared that information, allowing you to plan your season around buying video games.

The Summer kicks off with the isometric action-adventure Bastion on July 20, for 1200 Microsoft Points ($15.) Eric Chahi's volcanic god game, From Dust, follows on July 27 for the same price. On August 3, Insanely Twisted Shadow Planet wil be available, also for 1200 MSP. August 10 brings a refreshing virtual fruit salad in the form of Fruit Ninja Kinect, for 800 Points. Finally, Toy Soldiers: Cold War arrives on August 17 for 1200 Points.

Like previous years, there's a bonus for buying all five Summer of Arcade titles, and this year it's a free copy of Crimson Alliance when it's released on September 7 (for 1200 Points). Fruit Ninja Kinect's inclusion in the promotion means that you must have a Kinect in order to take advantage of the free bonus. That's a bummer of Arcade for those who haven't picked up Microsoft's camera yet.
